More 5G Than Man
As an opener? Just Pokey Lafarge and his band. They were fun.
He means the bands Jack rotates throughout the show. He has a male and a female group, and sometimes he mixes them.
He did a lot of mixing and matching throughout at Lollapalooza, it was interesting to watch. Dude has Captain Beefheart-level control of his band.
